Abundance of local actions for the vacuum Einstein equations

Michel Dubois-Violette, Mohamed Lagraa

We exhibit large classes of local actions for the vacuum Einstein equations. In presence of fermions, or more generally of matter which couple to the connection, these actions lead…

Coherent State Induced Star-Product on $R_{λ}^{3}$ and the Fuzzy Sphere

A. B. Hammou, M. Lagraa, M. M. Sheikh-Jabbari

Using the Hopf fibration and starting from a four dimensional noncommutative Moyal plane, $R_{θ}^{2} \times R_{θ}^{2}$ , we obtain a star-product for the noncommutative (fuzzy) $R_{λ}^{3}$ defin…
